Answer 1
Answer:
x = -5
Step-by-step explanation:
Solve for x:
3 x + 1 = -14
Subtract 1 from both sides:
3 x + (1 - 1) = -14 - 1
1 - 1 = 0:
3 x = -14 - 1
-14 - 1 = -15:
3 x = -15
Divide both sides of 3 x = -15 by 3:
(3 x)/3 = (-15)/3
3/3 = 1:
x = (-15)/3
The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:
Answer: x = -5
Answer 2
Answer:
Step-by-step explanation:
3x + 1 = -14;
substr 1 : 3x+1-1 = - 14 -1
3x = -15
divid by 3
x = -5

The temperature at 10 A.M is 12 degrees Fahrenheit. The temperature at 6:00 A.M. was -7 degrees Fahrenheit. How many degrees did the temperature rise?
Answers
The total temperature rise was 19 degrees.
What is Temperature?
Temperature express the measure of hotness and coldness, how hot matter is. It measure this thing in terms of any of several arbitrary scales like Fahrenheit temperature scale, absolute scale (kelvin) etc.
In the question statement, the temperature at 10 A.M is 12 degrees Fahrenheit. The temperature at 6:00 A.M. was -7 degrees Fahrenheit.
Here the difference in both the temperatures is as:
12 - (-7) = 21 degrees Fahrenheit
Hence there was an increase in temperature of 21 degrees Fahrenheit.

Find the mean, median, and mode of each set of values. 1.) Customers per day: 98 87 79 82 101 99 97 97 102 91 93
Answers
Put the values in order of least to greatest, and then eliminate numbers from each end until you’re left with one.
79, 82, 87, 91, 93, 97, 97, 98, 99, 101, 102
Median - Middle number, 97
Mode - Number that appears most often, 97
Mean - Add all numbers and then divide the total by the number of values in the data set, 93.3
Answer:
Mean = 93.3 ( to nearest tenth).
Median = 97.
Mode = 97.
Step-by-step explanation:
Arrange the data in ascending order:
79 82 87 91 93 97 97 98 99 101 102
There are 11 numbers.
The Median is the center value (= the 6th number) = 97.
The mode = highest occurring value = 97.
The mean = sum / 11 = 93.3.

Answers
3/8 multiplied by 4/5 forms the fraction 3/10
What is the required fraction ?
A fraction has numerator in top & denominator in bottom.
Given fractions are 3/8 & 4/5.
To multiply these two numbers, we have to multiply numerator of 3/8, i.e. 3 with numerator of 4/5, i.e. 4.
Also we have to multiply denominator of 3/8, i.e. 8 with denominator of 4/5, i.e. 5.
So, the new number be 3/8 × 4/5

Write 230.071 in expanded form
Answers
The third number to the left of the decimal is the hundreds, so you have 200.
The 2nd number to the left of the decimal is the tens, so you have 30.
The first number to the left of the decimal is the ones, and you have 0 ones, so you have 0.
The first number to the right of the decimal is the tenths place, which is 0 so it is 0.0
The second number to the right is the hundredths place, which is 0.07
The third number is the thousandths place, which is 0.001
The expanded form becomes:
200 + 30 + 0 + 0.0 + 0.07 + 0.001
Answer:
230.071 = 200 + 30 + 0.07 + 0.001
Step-by-step explanation:
First, make the following table.
Hundreds: 2
Tens: 3
Ones: 0
Decimal: .
Tenths: 0
Hundredths: 7
Thousandths: 1
With the help of this table, now it is easy to write the expanded form as follows
230.071 = 200 + 30 + 0.07 + 0.001
If square root of x has a decimal approximation of 3.4, then x is between which two integers? In your final answer, include all calculations.
Answers
Answer:
The integers between which x lies is:
11 and 12
Step-by-step explanation:
square root of x has a decimal approximation of 3.4
i.e.
We have to find the integers between which x lies
On squaring both sides, we get
x=11.56
Clearly, 11.56 lies between 11 and 12
Hence, the integers between which x lies is:
11 and 12
Answer:
You know that √x = 3.4, therefore x = 3.4² = 11.56
